Introduction

Scope of Manual

This instruction manual includes installation,

maintenance, and parts information for the Fisher

Lever-Lock handlever actuator (figure 1). Refer to

separate instruction manuals for information

covering the control valves.

Do not install, operate, or maintain a Lever-Lock

actuator without being fully trained and qualified in

valve, actuator, and accessory installation,

operation, and maintenance. To avoid personal

injury or property damage, it is important to carefully

read, understand, and follow all the contents of this

manual, including all safety cautions and warnings. If

you have any questions about these instructions,

contact your Emerson Process Management sales

office before proceeding.

Description

The Lever-Lock handlever is used for reliable

manual operation of DN 50 through 150 (NPS 2

through 6) Fisher A81 high-performance butterfly

valves. Spring-loading secures the handlever in the

notched quadrant plate (figure 2), allowing the valve

disk to be locked in intermediate positions.

Additionally, the handlever can be locked with a

user-supplied padlock with 4.8 to 5.2 mm

(3/16 to 13/64 inch) shackle to prevent accidental or

unauthorized adjustment (see figures 3 and 4).

Installation

The Lever-Lock handlever actuator is normally

shipped mounted on the valve at the factory. If the

handlever was ordered separately, install the

handlever on the valve by following the instructions

in this section.

WARNING

Sudden or unexpected movement of

the handle can result from unbalanced

flow forces. Firmly grip the handlever

and ensure stable footing when

operating the handlever to avoid

personal injury or property damage.

Installing the Handlever

Orientation

Mount the Lever-Lock bracket assembly, less the

handle, to the valve body. The handle is

perpendicular to the pipeline when the valve is in the

shut position. Rotation of the lever/valve shaft in the

counter-clockwise direction will open the valve.

Attach the Lever-Lock Handlever actuator to the

valve in this orientation but do not fully tighten

(torque) the bracket to valve bolting until after the

zeroing process below.

Handle assembly

Place the handle and lever assembly on the valve

shaft with the valve closed. Squeeze the lever to

compress the spring, position the lever over the

notch indicating the closed position, and slide the

square cutout portion of the handle over the valve

shaft as far as it will go. Maintain at least a 0.8 mm

(1/32 inch) gap between the handle and the plate, so

the handle doesn’t rub on the plate during operation.

Torque the two hex socket set screws against the

shaft to 2.7 NSm (24 inSlbf).

Zeroing

After tightening the set screws, check the orientation

of the disk relative to the body seal retainer. Place a

straight edge on the seal retainer which spans the

valve opening. Visually check to ensure there is

equal space (within 0.8 mm [1/32 inch]) between this

straight edge and the top and bottom of the disk to

ensure the valve is fully engaged in the seal. To

adjust this position, rotate the bracket within the

clearance of the mounting bolt holes between the

valve body and bracket. Once there is equal

distance between the disk and the straight edge,

tighten the mounting bolts to 115 NSm (88 ftSlbf).

After tightening, recheck disk position at shutoff to

ensure nothing shifted during the tightening process.

Maintenance

Handlever parts are subject to normal

wear/corrosion and must be inspected and replaced

when necessary. The frequency of inspection and

replacement depends on the severity of service

conditions.

WARNING

Avoid personal injury or damage to

property from sudden release of

pressure or uncontrolled process fluid.

Before starting disassembly:

D Do not remove the actuator from

the valve while the valve is still

pressurized.

D Always wear protective gloves,

clothing, and eyewear when

performing any maintenance

operations to avoid personal injury.

D Use bypass valves or completely

shut off the process to isolate the

valve from process pressure. Relieve

process pressure on both sides of the

valve. Drain the process media from

either side of the valve.

D Use lock-out procedures to be

sure that the above measures stay in

effect while you work on the

equipment.

D The valve packing box may

contain process fluids that are

pressurized, even when the valve has

been removed from the pipeline.

Process fluids may spray out under

pressure when removing the packing

hardware or packing rings, or when

loosening the packing box pipe plug.

D Check with your process or safety

engineer for any additional measures

that must be taken to protect against

process media.
